    I am having problem in binding to the Datacontext at viewdefinition level, It works if i create my viewmodel in xaml and set the DataContext of the grid using staticresource, but if i set the datacontext to the window in code behind it does not work

                    <schedule:DayViewDefinition GroupFilter="{Binding GroupFilter2}"/>
                    <schedule:WeekViewDefinition GroupFilter="{Binding GroupFilter2}"/>
                    <schedule:MonthViewDefinition GroupFilter="{Binding GroupFilter2}"/>

    ----------- this does not work, does no bind to Group Filter -----------------
    public MainWindow()
                this.DataContext = new ViewModel();

    ----------- this works -------------------

            <local:ViewModel x:Key="ViewModel" AppointmentsSource="/Schedule;component/Appointments.xaml" />
    <Grid x:Name="mainGrid" DataContext="{StaticResource ViewModel">

    Hi Vikas,

    In order to get the binding working correctly you would need to either set the DataContext in XAML or above the InitializeComponent in the constructor of the MainWindow:

    public MainWindow()
        this.DataContext = new ViewModel();

    Hope this helps.
